Full TCP/IP connectivity through management interface (Telnet, FTP, etc.) Flexible Packet Generation Each Ixia 10GE XM test port is capable of generating precisely controlled network traffic at up to wire-speed of the network interface. Up to millions of packet flows can be configured on each port with fully customizable packet header fields. Flexible header control is available for Ethernet, IPv4/v6, IPX, ARP, TCP, UDP, VLANs, QinQ, MPLS, GRE, and many others. Payload contents can also be customized with incrementing/decrementing, fixed, random, or userdefined information. Frame sizes can be fixed, vary according to a pattern, or be randomly assigned across a weighted range. Rate control can be flexibly defined in frames per second, bits per second, percentage of line rate, or inter-packet gap time. Real-Time Latency and Jitter Analysis Packets representing different traffic profiles can be associated with Packet Group Identifiers (PGIDs). The receiving port measures the minimum, maximum, and average latency in real-time for each packet belonging to different groups. Measurable latencies include: - Instantaneous latency and inter-arrival time where each packet is associated with one group ID - Latency bins, where PGIDs can be associated with a latency range - Latency over time, where multiple PGIDs can be placed in "time buckets" with fixed durations - First and last timestamps, where each PGID can store the timestamps of first and last received packets P/N: Rev.

6 Transmit Scheduler There are two modes of transmission are available - Packet Stream and Advanced Stream Scheduler: Packet Stream Scheduler In Packet Stream Scheduler mode, the transmit engine allows configuration of up to 256 unique sequential stream groupings on each port. Multiple streams can be defined in sequence each containing multiple packet flows defined by unique characteristics. After transmission of all packets in the first stream, control is passed to the next defined stream in the sequence. After reaching the last stream in the sequence, transmission may either cease or control may be passed on to any other stream in the sequence. Therefore, multiple streams are cycled through, representing different traffic profiles to simulate real network traffic. Advanced Stream Scheduler In Advanced Stream Scheduler mode, the transmission of stream groupings are interleaved per port. For example, assume a port is configured with three streams. If Stream 1 is defined with IP packets at 20% of line rate, Stream 2 is defined with TCP packets at 50% of line rate, and Stream 3 is defined with MPLS packets at 30% of line rate, data on the port will be transmitted at an aggregate utilization of 100% with interleaved IP, TCP, and MPLS packets. Extensive Statistics - Real-time 64-bit frame counts and rates - Spreadsheet presentation format for convenient manipulation of statistics counters - Eight Quality of Service counters (supporting 802.1p, DSCP, and IPv4 TOS measurements) - Six user-defined statistics that use a trigger condition - Extended statistics for ARP, ICMP, BGP, OSPF, IS-IS, RSVP-TE, and LDP - Transmit stream statistics for frame counts and rate - External logging to file for statistics and alerts - Audible and visual alerts with user-definable thresholds Data Capture Each 10 Gigabit Ethernet XM port is equipped with 350 MB of capture memory (32MB for the LSM10GXMR3). The capture buffer can be configured to store packets based on user-defined trigger and filter conditions. Decodes for IPv4, IPv6, UDP, ARP, BGP-4, IS-IS, OSPF, TCP, DHCP, IPX, RIP, IGMP, CISCO ISL, VLAN, and MPLS are provided. P/N: Rev. A Page 6 of 8

7 Data Integrity As packets traverse through networks, IP header contents may change resulting in the recalculation of packet CRC values. To validate device performance, the data integrity function of the 10GE XM modules allows packet payload contents to be verified with a unique CRC that is independent of the packet CRC. This ensures that the payload is not disturbed as the device changes header fields. Sequence and Duplicate Packet Checking Sequence numbers can be inserted at a user-defined offset in the payload of each transmitted packet. Upon receipt of the packets through the Device Under Test (DUT), out-of sequence errors or duplicated packets are reported in real time at wire-speed rates. The user can define a sequence error threshold to distinguish between small versus big errors, and the receive port can measure the amount of small, big, reversed, and total errors. Alternatively, the user can use the duplicate packet detection mode to observe that multiple packets with the same sequence number are received and analyzed. Routing/Bridging Protocol Emulation Ixia's 10 Gigabit Ethernet XM modules support performance and functionality testing using routing/bridging protocol emulation via the Aptixia IxNetwork and Aptixia IxAutomate applications. Protocol support includes IPv4/IPv6 routing (BGP-4, OSPF, IS-IS, and RIP), MPLS (RSVP-TE, LDP, L2 MPLS VPNs, L3 MPLS VPNs, and VPLS), multicast (IGMP, MLD, and PIM-SM), and bridging (STP, RSTP, MSTP). Highly scalable scenarios can be created emulating up to thousands of routers advertising millions of routes per test port. Up to wire speed Layer 2/3 traffic can be automatically created to target routes and MPLS tunnels. Application Layer Performance Testing Ixia's 10 Gigabit Ethernet XM modules support high performance testing of content-aware devices and networks via the Aptixia IxLoad application. IxLoad creates real world traffic scenarios at the TCP/UDP (Layer 4) and Application (Layer 7) layers, emulating clients and servers for Web (HTTP, SSL), FTP, (SMTP, POP3, IMAP), Streaming (RTP, RTSP), Video (MPEG2, MPEG4, IGMP), Voice (SIP, MGCP), and services such as DNS, DHCP, LDAP and Telnet. Each GXM port can be independently configured to run different protocols and client/server scenarios. In-Line Network Monitoring P/N: Rev. A Page 7 of 8

8 The 10 Gigabit Ethernet XM modules can be configured to be used in-line with the network and can passively monitor at full wire speed. This feature is useful for network troubleshooting and eliminates the need for optical splitters. Tcl API Ixia s 10GE XM modules are fully supported by a comprehensive Tcl Application Programming Interface (API). This API allows users to develop custom scripts and integrate the modules into automated test environments. Custom Applications The Linux Software Development Kit (SDK) allows existing Linux applications to be compiled and run on 10GE XM ports. Additionally, users can develop their own custom applications and integrate them into the Ixia test environment.
